Trickle down was a Reagan thing.
I'm very confused by your statements.
I mean it was the Big Beautiful Bill that just added 3-5 trillion in debt and reduced taxes on the very wealthy. I don't think those impotent Dems had any sway in this.
Then you're too focused on political concerns. Neoliberalism doesn't recognize political parties, it recognizes money. As Gore Vidal would say, the Property party.
Neoliberalism, trickle down, abundance. They are all similar and/or the same.
Dems are also beholden to the wealthy--not sure they tried that hard, overall.
